CINCINNATI, Ohio – The crisp calm of fall mornings is about to turn frosty across the Ohio River Valley. Under clear skies and light winds, temperatures are poised to dip near freezing by early Friday, marking the first widespread frost of the season for the Tri-State region.
According to the National Weather Service in Wilmington, a Frost and Freeze Watch is in effect late Thursday night through early Friday across east-central Indiana, northern Kentucky, and southwest Ohio — including Butler, Warren, Hamilton, and Boone Counties. Calm winds and low humidity will allow heat to escape quickly, sending readings into the mid-30s, and even near 32°F in rural pockets outside the Cincinnati metro.
Residents should protect sensitive plants and outdoor plumbing, and bring pets inside before temperatures drop. Commuters along I-75 and I-71 should allow extra time Friday morning as frost may coat windshields and create slick spots on elevated surfaces. For gardeners, this could be the season’s turning point — the signal to clear beds and prepare for winter soil rest.
Thursday will feature sunny skies and mild afternoon air, peaking near 59°F before the sharp cool-down begins after sunset. Friday stays crisp and bright, while the weekend warms slightly with highs near 60°F under partly cloudy skies. It’s prime weather for pumpkin patches and Halloween decorating, though many will feel that familiar bite in the air hinting that winter’s not far off.
To be fair, there’s no snow in sight yet, but across the Midwest — from Wisconsin to Ohio — folks are starting to look north and wonder when the first flakes might fall.
